WALANT Surgery Works for Ankle Fractures
OrthoBuzz previously covered WALANT (wide awake, local anesthesia, no tourniquet) surgery, and we very recently featured a JBJS study about treating ankle fractures in a limited-resource environment. These 2 concepts unite in a JBJS study by Tahir et al., which reports on WALANT surgery for ankle fractures in Pakistan.
WALANT surgery has enjoyed increasingly broad dissemination throughout the world since its popularization by Canadian hand surgeon Don Lalonde. Considering its origins, WALANT has been adopted most enthusiastically by the hand-surgery community, but it has been applied successfully to other anatomic regions. WALANT principles are particularly relevant in settings where anesthetic resources and expertise may be limited, such as hospitals where monitoring equipment that helps ensure safe general anesthesia is not readily available.
Tahir et al. used WALANT during open reduction/internal fixation (ORIF) in 58 patients (average age of 47 years) with a distal fibula fracture; 62% of those fractures were OTA-classified as 44C2. Among the excellent results in this cohort were a mean intraoperative VAS pain score of 1.24 and a mean operative time of <1 hour. These findings point to the potential for safely using WALANT techniques during ORIF of other fracture types.
The authors emphasize, however, that “each patient should be individually assessed by the operating surgeon,” not only for injury characteristics that contraindicate WALANT, such as substantial swelling, but also for anxiety and psychological disorders. Consequently, Tahir et al. recommend that surgeons undertaking WALANT procedures have a backup anesthetist available so they can convert to general anesthesia in cases of patient anxiety.
